We also saw some problems with recent Dell machines with ?SpeedStep? or whatever
Intel calls their power/speed management these days.

One developer measured a very significant increase in speed after completely
disabling support for it in his kernel on multiple Linux variants.

I don?t have the details from him, but he said the system went from ?almost
unusable on a daily basis?, to, ?I can actually get things done?.

He mainly uses it as a desktop replacement, so he didn?t care about any benefits
from power management to save battery, etc.

Very ?informal? note? I don?t have the data to turn in bug reports, or time to
chase it down.

He shared what he did informally with a couple of other devs and ?hallway
discussions? have indicated that they also agreed that they had better
performance from the machines.

Hello All,

installing these laptops went ok, but indeed, they shutdown on logon.
When coming back up, I get a bios warning about temperature.
On my first attempt on installing Nvidia driver, I wrecked the laptop.
To be continued.

greetings, Johan

Hi,

Thanks for your feedback. I can't say I'm "happy" that someone
else is
having the same problem, but I'm relieved that it's not just something
odd with the setup I am using.

Any luck? I'm hoping to have a chance to look more into this myself in
the next few weeks once some other projects calm down. Ironically my
next step was going to be going after an updated video card driver.

Hello Deoren,

adding elrepo and installing kmod-nvidia seems to have solved the issue.
I hope this works for you as wel.

greetings, Johan
